TDK Corporation has developed the new TFM201208BLE series inductors to optimize power supply circuits for smartphones where space is limited. These inductors are available in 0.24, 0.33, and 0.47 µH versions, and mass production will begin in June 2022.
TDK's latest series of inductor products, with an external dimension of 2.0 (L) x 1.2 (W) x 0.8 (H), has better electrical performance than previous TFM201208BLD products in terms of current and resistance levels. Compared with conventional products, this series has a rated current of 5.5 A (Isat), a 10% increase, and a DC resistance of 25 mΩ, a 22% decrease. *These parameters are the best in the industry for this size inductor. ** Significant performance improvement is achieved through TDK's innovative metal magnetic material technology and structural design.
As smartphone performance continues to improve, system-on-chips (SoCs) with increased arithmetic throughput will be required, and accompanying passive components must exhibit higher current characteristics. In addition, smartphone designs integrate more and more functions, resulting in an increasing number of power circuits involved. Therefore, the inductor used must have low resistance and minimal losses in order to prolong battery life. The TFM201208BLE family provides much-needed value to smartphone original equipment manufacturers (OEMs), as well as the necessary high current and low resistance.
